<div dir="ltr">Hi Simon,
<div>It looks like a very nice software, thanks for sharing. I
started to play around with it but a simple read an image and
then rotate, got me an error (see below). I need to open a
ticket for this issue in the MPDAF webpage, however it seems
very inconvenient as you need to create an account with CRAL
first. <br>

Yes, sorry about that .. <br>
But we also have a mailing list, I can transfer you email there to
avoid spamming Astropy's list, and try to find the bug (we use
mostly MUSE and HST data so it is possible that some wcs stuff is
not well handled for your data).<span class="HOEnZb"><font color="#888888"><br>

</p>
<p>It uses scipy.ndimage.affine_transform<wbr>, and
should give the same result as reproject, which uses
scipy.ndimage.map_coordinates (both rely on
ndimage.geometric_transform). It would be interesting
to compare ! <br>

<div>Hi Marcio,<br>
<br>

While it doesn't do exactly what you ask
for, you may want to check out the
affiliated package reproject (<a href="http://reproject.readthedocs.io/en/stable/" target="_blank">http://reproject.readthedocs.<wbr>io/en/stable/</a>).
It does flux conserving image
